Arctic land

How could an arctic land be used in a fantasy story? I have worldbuilded a region in the northernmost part of my continent where the land is always snow and ice, its similar to Forodwaith.
The only interesting thing about this land are inuit-like tribes; silver-skinned, ice-breathing "wyverns" and polar bears.
Because I want to be realistic, there are no trees in this arctic land.

Since very few people live in a arctic lands (both in reality and fantasy) and my story is from the perspective of humans, what could make the arctic land be involved in the story?

It wasn't always a Frozen land.... maybe there are artefacts or ruins of lost civilisations?
If there are few people, use the isolation and loneliness. To those not born to it or suited for it, it might have funny/disturbing effects. The cold, the wind, the endless days and endless nights.

Since you mention Forodwaith, I'm sure you know that King Arvedui fled there after he was defeated in battle where the Lossoth helped him. (It only didn't work out well for him because he didn't listen to their advice.)

In Lev Grossman's The Magicians, the magician's school had a secluded training facility in the Antarctic where they could be sure no one would notice a bunch of teenagers turning into foxes and whatnot.

In Lovecraft's The Mountains of Madness, a team of scientists when there to explore and research and ended up stumbling on the ruins of an incredibly ancient civilization.

In Tad Williams' Memory, Sorrow and Thorn series the main character meets a "troll" from the far north (essentially equivalent to the Inuit) and at one point along their quest they go to the troll's home to rest and resupply.

But really all you have to do is look at our own world. Because people DO go to the arctic. They go for exploration and discovery. Humans have always just wanted to know what's out there and what the world looks like. They go to find resources that can be used. They go to conduct scientific research. And they live as close to the arctic as they possibly can simply because they need somewhere to make their home. There are plenty of reasons. You just have to use your imagination.

On a much more mundane level, the arctic (and antarctic) of this world at least are a prolific food source around the coastal edges. Other resources are usually hidden far beneath the ice. Layers of ice are great at hiding all manner of things. I just finished re-reading Robin Hobbs Fool's Fate, and half the book is spent on an ice bound island far to the north, where the characters must dig up and/or kill a Dragon.

Maybe your arctic land is the last remaining source of freshwater in your world? Maybe its not actually polar at all and is a great swath of ice caused by some long ago magical cataclysm and your characters have to learn what caused it? Maybe a thief of an important artifact goes there to try and hide from your protagonist (or flip it: your protagonist steals an artifact of great power and must find a way to hide it from your villain)?

I'm just spit-balling here .

P.S. when you don't have any trees, the droppings from grass eaters make a good fuel source when dried out XD.
